macnmn notation Toyajl'l 'whom it may concern." c v Be it known that,I,; ARTHUR J. Ronon a citizen ofthe United States, and a resi dent of the city-of Cincinnati inthe county of Hamilton and State :of' 'hio, have in vented certain l newand useful Improvements in Machines for .Wrapping, Candy, of

' which the followin isa full, clear, and exact description, re erencebeing'had to the" accompanying drawings, forming part of this-specification.

' My lnvention' relates to machines for-an tomatically feeding wrapping paper toand wrapping "candy,--a.nd has particular refer-9 ence to machines for wrapping stick candy, 1 in which the wrapping paper isjrolled'on the candy and twistedat' the ends. I

My invention consists of .that certain .novel construction and arrangement of 'rnechanical parts to be hereinafter particularly pointed out and claimed, whereby' the sticks of candy and the wrapping papenin sheets are automatically fed 'to the inachIne,'-.one stick and: one sheet of paper at a time-to be .rolled, and thef' ends twisted and the wrapped sticksdelivered from the machine.

In the drawings, Figure 1 is 'afs'ide eljeva tion' ofzmy improved machine. Fig." 2 is a front elevation of thesame. Fig. 3 is a central longitudinal section. Fig iris a top plan View of the front portion of themachine,-with the main operating shaft removed. Fig; 5 'is aside elevation of the opposite side of the machine to that shownmwrappedicandy" fron r the machine. I ig 7 is a detail sidejeleya'tion of one of the'grippers for twisting the paper andits operatmechanism.-

Mounted n ,suitable side supports 2, is the main oper ating shaft 30f the machine, and upon this 'shaft 'midway'betwe'en the side standards are. mounted apair -of cam disks 4:; 5. These cam disksare'eachprovided with'a resilient peripheral band 6, which is bolted at 7, 7," on the flat portion of the outer edge of each cfll ,'and extends around thecamsurface and is'pre'ferably covered with leather 8. The 'resilient" hands are supported by springsfi, and as the cams are brought into will'be shown by the arrows 'iin Fig,

each of these shafts 13, 14, is'pro v:ided with a pinipn l5, l6,- and these p'inio'ns are errgagcd by'. afiridl'er' pinion 17, which is driven -by the gear 18, secured to the/shaft 3. (see. ig.- i')-. T e haf and h -g a 1 driven in the direction of. the arrdw shown; :in Fig. 5,",and it will be: ev,identjthat.the

roller shaft's '1 3 and '14.- ahd the: roller will both be driven in the same ,direc'ti-om'. as also suitable method of; driving "the n Fig.1 a motor 19, with belt-20, fo -"drivi this shaft.

Mounted to the rear of the rolleis in the framework is an inclined trough. 21,

ingof suitable size to holda considerable 5 'ng h fl '3 may he provided, and I have-indicated in number of sticks; The candy is-held in the trough by means of two fingers 23, 94, which 'pro e ct/upwardly andinnormal position ere tend a short distance above the floor of the 'trough. These fingers 23, 24, are mounted "on a shaft 25, which. is carried: by arms 26, pivoted to and depending from the bars 27, Y

28, which are pivot-ally mounted at 29, 30 5f.

in the rear of the framework. These' jbars' vare normally held in horizontalposition by coiled springs 31, attached to-each bar an ,to a bracket 32 extending out. from the framework. Secured on the shaft 3 at either end are the arms'34, 35, carrying rollers'33, 83, which project in line with these bars27,"

28, and asthe shaft 3 'is rotatecL-the rollers in proper timed relation with the other parts of the mechanism come in contact with the bars- 27,28, anddepress them, thus re-f tractin'g the fingers 23 from, in; frontfo'f the '1' foremost stick of candy, allowing. the stick to move forward in the trough over the fingers and resting againsta fixed bar 36 located transverse the floor of thetroug'h.

This'foremost stickof candy remainsrm this position-until the arms;.34"relea se -the;

'oted at on across bar of the framework,

and the plate is provided with a shield portion which extends out over the spa 1 between the rollers and 11, and car an upwardly projecting portion at), which serves as a guide for the wrapping paper as will behereinafter described. The guard plate 37 is also provided with an extension 41, which is carried upwardly, embracing the shaft 3, around a cam 42 secured to the shaft 3, which cam is so arranged that at the proper time it will come in contact with the extension 41 and raise the guard plate. Projocting from the cam disks 4, 5, in opposite directions, area pair of fingers 43, 44-, and the cam disks are so mounted on the shaft 3 that the fingers 43 shall have passed the end of the trough before the forward stick of candy reachesthis position. The rear set of fingers 44, however, come in contactwith they-stick and push it off the end of the trough, allowing it to drop down between the rollers 10 and 11. The movement of the rollers causes the stick of candy to rotate when it comes in contact With the upper surface thcreof,and these rollers are preferably covered with leather or rubber to prevent "injury to the candy.

The momenta stick of candy is delivered to the rollers, a sheet of wrapping paper is alsopresented to the rollers from the front of the machine. The paper sheets 45, of proper length andwidth for the wrapper, are -'inounted in a rectangular "receptacle with fixed side and end Walls i7, 48, and resting upon the upper portion of anpendless belt 4.9, which is extended across the bottom of the receptacle over rollers 50, 51, mounted torotate on axle boxes 52, which are mo'unted on vertical studs 53, projecting upward from'a transverse bar of the frame work, and these axle boxes for the rollers are sustained by coiled springs 54- (Fig. '2).

Resting on top of these rollers are the straps 55, 56, which are coupled to the ends of a horizontal equalizer bar 57, pivoted at 58 to a leverf59, one end of which is pivoted at 60 to the lower portion of the framework, and the other end connected by a strap 61, secured atits upper end to a horizontal bar 62, pivotally mounted in the front of the framework, which bar 62 at its other end is' wrapping paper. The purpose of this air 131mm) construction to furnish suction at the proper moment-to draw upwardly the foremost sheetfrom the package of paper to enable it to be grasped by the feed frame 63?. This feed frame is provided with a transverse push bar 70, against the edge of which the upper sheet of paper is drawn by the suction of the air pump. At the same time that the suction of the air pump draws upwardly the uppermost sicet of paper, the

movement of the bar depresses the free end of the lcrer 59, so that through the equalizer bar 57 and the straps 55, 56, the rollers 50, 51, carrying the endless belt, arev drawn dowmvardly. A weight 71. isinounted on the under loop of the belt 49, so that as the rollers are drawn' down compressing the springs 54," the package of sheets of wrapping paper, except the uppermostsheet, is lowered. During the opposite stroke of the air pump, the pressure on the rollers 50, 51, is removed, the springs 5i raise the rollers and the weight 71 tightens the belt to raise the package of paper. The frame 69 is guided inslots 72 in the framework of the machine, and this feeding frame is coupled by links 73 with the arms 7el secured to the horizontal shaft 75 journaled on standards in the framework, and this shaft 75 carries a cam 76, which is projected into the pathway of an arm 77 on the shaft 8, the parts being so arranged that the cam will be actuated by the arm to rock the shaft 75 in proper timed relation to the other movements of the machine. The rocking 0f the shaft 75 causes the arms 74- to slide the frame 69 forward, thus feeding forward the uppermost sheet of paper. Springs 7 8 return the feeding frame to its normal position when the cam 76 is released from the arm 7 7. The front edge of the paper sheet is, by the movement of the feeding frame, brought against the guiding surface 40 and over the roller 10, at the same time that the stick of candy reaches the position between the rollers, and the movement of the rollers causes the paper to wrap around the candy. Opposite the ends of the stick candy, be-

tween the rolls, are a pair of grippers 79, 80. Each of these grippers comprises two members (Fig. 7) 8-1, 82, with a wide gripping bar 83. These grimuing members are pivoted on a transverse spindle 84:."lVhlCh is mounted at either end on parallel rods 85, 86, so that the spindle can slide on the rods 85, S6, and thus carry the grippers forward toward the rollers 10, 11.. Coiled springs 87, 87, hold the grippers normally away from the ends of the rollers; In order to actuate the grippers, I provide the transverse bar 88, which is also mounted .to slide on the rods 85, 86, and this bar is-pushed forward by the vertical edge of a movable wedge 89, which is actuated verticallv. and

v-ei rat'w shearing and is guided by the fianges managerial-a slotlinfihe upper face of the th surface of the bar ,88 "between grippers. are; clgsed the'I-turther "downward movement of the red e'plates .will; carry the grippersfinwardly toward th'e'e'nds oft-he rollers. Q ,The obj ect off ithi s', as will h e-hereh' after described, that the grippers, after they have grasped the wrapping paper'- as it iswrapped around the candy," may hold the paper while the 'wrapperis twisted, and inasmuch as the twisting of'th'e paper shortens the length of the wrapper thegrippers are advanced t -oward, .the rollers during. the

twisting operation'ixigordei' to prevent the paper from tearing.

When the pandy has been wrapped, the package 'isipus'hed' from the position between the rollers .10 and 11 by the pusher shown in Fig, 6,'which'con1prises.a pair of angle plates 91," mountedron rods 92, held to 1 slide back an'd forthi inbrackets 93, mounted "underneath the delivery. trough on each side. ,Coiled springs Mare mounted on the rods 92between one arm of the brackets and a i'od'95 w hieh connects the two d 92.

Pivoted at 96'on each side of the delivery trongh are two levers 97, 97, the lower ends of which bear against the rod 95, and the othere (1s 98 extend npwardlvin the path- .wayfo- ;a ms 99, 99,'sec'ured to the shaft 3, so thatat the proper timethe arms coming in contact with the levers 97' shiftthe ngle' 'pltes 91 into the position shown by c otted lines in Fig.0, to deliver the wrapped package from the machine.

The operation of the various mechanisms in their timed relation to each other is as follows: Sticks of. candy 22- are-l'aid in the trough, the foremost stick resting against the fingers :23, with-the parts in the position'shown in Figs. 1 and 3. Let us assumem that one stick of candy has been wrapped and. deliyered, and the next succeeding stick has been delivered by the fingers 23 in front of the bar, 1th the machine now set in operation, this unwrapped stick is carr ed bythe cam disks to thefront edge of the v i wedge plate" 90ff' The movable wedge-plate 89 are fpivoted nearthe outer eiids-ofithe bars 27,128,,th-e connection being ateiiflTflh' result of this isthatias 2T, are depressed as heretofore he wedge plates will be, depressed;

.soon as the arms 27, 28, are released by the crank arms34, 35, the springs 31-retract thearms and with them the wedge plates 89,

90, and a small spring located between the outer ends of the grippers (not shown) opens 'the grippers, releasing thewrapped stick, and-the deliver plates 91 are'oper; ated', assisted by the ngers 43 on-the cam disks 4, 5, to deliver the wra ped candy i from the machine, whence it rops down into a suitable receptacle, or into a eonveyer (not shown).
